The use and function are similar to the ubiquitous VHS video cassette. Random access cassette (RAC) is a sealed (for cleanliness) mechanical disk and head module or cassette. The electronics are retained in the host device. Removable media would be treated just like a cassette, with the advantage that this cassette has random access of the storage. The very high density of our HDDs today have allowed us to store movies on "Set-Top" boxes. The problem is that the storage is limited because it is not removable. With the RAC cassette, a single movie can be recorded and kept in a personal library. The same concept can be applied to audio, pictures or video storage like on a cassette today. A very small amount of information is stored with the RAC to allow custom interfacing to the electronic module. 1
